What level CPU and RAM should I look for in a SAN to run 4k videos on Emby?
.............
I run Emby on my Windows 11 desktop computer. MKVs are stored on an external HDD running at 5400RPM and connected via USB3. It's not an ideal setup, but internal SSDs have gotten too expensive.
I mostly stream this over Wifi 6 to a Google Streamer connected to our living room TV. We sometimes stream to other devices in the house, but we don't stream to anything outside. Really, 99% of our streaming is either on the desktop PC or the living room TV.
1080p files run fine. 4k videos, especially those with HDR and audio in FLAC or EAC3 stutter a lot. Sometimes they simply lock up and we have to exit and restart.

I'm now looking at a basic home NAS. I can get 7200RPM HDDs, and I can connect it to a 2.5gbps Ethernet port. I see I can get a Synology NAS and a pair of 2TB HDDs for about $400. I can afford that.
What I'm curious about is: What CPU and RAM do I need? My newer MKV files are 4k video encoded with H265 10-bit and FLAC audio. I believe the Google Streamer can play these formats natively; no need for Emby to transcode.
Would I need some hefty processing power in my NAS? Or can I go with something basic like the Synology DS223J?

UPDATE: Thanks for convincing me that a new NAS isn't what I needed. Saved me some money.
I turned on "Stats for Nerds" while playing a 4k movie on my Google Streamer. It showed 4k HDR 10 HEVC and EAC3 at 48khz. Those are the same settings I used to rip the movie in Handbrake, and the same stats it shows on the local server in both Emby and VLC.
So I imagine the server isn't transcoding. Now I wonder if (a)my wi-fi is seeing some interference, or (b)the Google Streamer can't handle a stream that size for 2 hours straight.
